This highly interactive and advanced course will give you insight into the most common Python tricks and tips. This course is for practicing Python programmers who are aiming for proficiency in Python 3. If you want to switch from Python 2 to Python 3, this is your go-to course. 

This course will help you learn the Pythonic Way of writing code and leveraging advanced robust features to become more proficient than the average developer. You’ll start by covering Python’s built-in data structures, and then you’ll move on to different programming paradigms like functional programming and object-oriented programming. 

In the latter half of the course, you’ll focus on iterables, generators, and coroutines. You’ll also have the opportunity to work on two projects to help strengthen what you learn. In all, this course is perfect for anyone who wants to become a confident and competent Pythonista by picking up the idioms and practical tips.

## Task 1: Read matrix from a file

The task is to read the matrix from a file. This task has some specifications. The file should follow a specific format. For example, you can have:
```txt
1 2 3
4 5 6
7 8 9
```
The format of the file is up to you. 
The above data can be mapped as:


Write a function `read_matrix(filename)`, where the `filename` is the name of the file containing the matrix.  The function should read the file using the _context manager_ protocol into a _nested list_. If we read the above file, we should get the list as: __[[1, 2, 3], [4, 5, 6], [7, 8, 9]]__.  

> 🧐 __Note__: Assume that data in the file is always a matrix. 

That's not the end yet. You have to create a `Matrix` object. The instance of `Matrix` class will only contain the nested list.

---
## Task 2: Print the matrix
The simplest way to print the matrix is to print its nested list. If you wish to print a better visualization, it's up to you. Print the matrix whenever `print` is called on the `Matrix` object.

---
## Task 3: Add the matrix
This task is a little complicated. You have to overload the `+` operator to add two matrices. 

> ✏️ __Note__: Originally, there are two text files, each containing a matrix. You can read both files and add the matrices you get. Or, you can create your test matrices using the `Matrix()` class. It's up to you.

Don't forget to cover the edge cases that restrict the addition. For example, the order of matrices needs to be the same. Do raise the error for the cases that aren't allowed. 

Here's the critical part. Add two matrices, and if the addition is successful, only then print the result. Otherwise, raise the exception: __Addition not possible!__

> ❌ __Note__: You cannot add a scalar to a matrix. For example: `1 + matrix` or `matrix + 1` isn't allowed. Do not forget to handle this case.
